Thesis (PhD)--Stellenbosch University, 2015 / AFRIKAANSE OPSOMMING : In hierdie verhandeling stel ons 'n nuwe strategie vir outomatiese handtekening-verifikasie voor. Die voorgestelde raamwerk gebruik 'n skrywer-onafhanklike benadering tot handtekening-
modellering en is dus in staat om bevraagtekende handtekeninge, wat aan enige
skrywer behoort, te bekragtig, op voorwaarde dat minstens een outentieke voorbeeld vir
vergelykingsdoeleindes beskikbaar is. Ons ondersoek die tradisionele statiese geval (waarin
'n bestaande pen-op-papier handtekening vanuit 'n versyferde dokument onttrek word),
asook die toenemend gewilde dinamiese geval (waarin handtekeningdata outomaties tydens
ondertekening m.b.v. gespesialiseerde elektroniese hardeware bekom word). Die
statiese kenmerk-onttrekkingstegniek behels die berekening van verskeie diskrete Radontransform
(DRT) projeksies, terwyl dinamiese handtekeninge deur verskeie ruimtelike en
temporele funksie-kenmerke in die kenmerkruimte voorgestel word. Ten einde skryweronafhanklike
handtekening-ontleding te bewerkstellig, word hierdie kenmerkstelle na 'n
verskil-gebaseerde voorstelling d.m.v. 'n geskikte digotomie-transformasie omgeskakel.
Die klassikasietegnieke, wat vir handtekeking-modellering en -verifikasie gebruik word,
sluit kwadratiese diskriminant-analise (KDA) en steunvektormasjiene (SVMe) in. Die
hoofbydraes van hierdie studie sluit twee nuwe tegnieke, wat op die bou van 'n robuuste
skrywer-onafhanklike handtekeningmodel gerig is, in. Die eerste, 'n dinamiese tydsverbuiging
digotomie-transformasie vir statiese handtekening-voorstelling, is in staat om vir redelike
intra-klas variasie te kompenseer, deur die DRT-projeksies voor vergelyking nie-lineêr
te belyn. Die tweede, 'n skrywer-spesieke verskil-normaliseringstrategie, is in staat om
inter-klas skeibaarheid in die verskilruimte te verbeter deur slegs streng relevante statistieke
tydens die normalisering van verskil-vektore te beskou. Die normaliseringstrategie is generies
van aard in die sin dat dit ewe veel van toepassing op beide statiese en dinamiese
handtekening-modelkonstruksie is. Die stelsels wat in hierdie studie ontwikkel is, is spesi
ek op die opsporing van hoë-kwaliteit vervalsings gerig. Stelselvaardigheid-afskatting
word met behulp van 'n omvattende eksperimentele protokol bewerkstellig. Verskeie groot
handtekening-datastelle is oorweeg. In beide die statiese en dinamiese gevalle vaar die
voorgestelde SVM-gebaseerde stelsel beter as die voorgestelde KDA-gebaseerde stelsel.
Ons toon ook aan dat die stelsels wat in hierdie studie ontwikkel is, die meeste bestaande
stelsels wat op dieselfde datastelle ge evalueer is, oortref. Dit is selfs meer belangrik om
daarop te let dat, wanneer hierdie stelsels met bestaande tegnieke in die literatuur vergelyk
word, ons aantoon dat die gebruik van die nuwe tegnieke, soos in hierdie studie voorgestel,
konsekwent tot 'n statisties beduidende verbetering in stelselvaardigheid lei. / ENGLISH ABSTRACT : In this dissertation we present a novel strategy for automatic handwritten signature verification. The proposed framework employs a writer-independent approach to signature
modelling and is therefore capable of authenticating questioned signatures claimed to belong
to any writer, provided that at least one authentic sample of said writer's signature
is available for comparison. We investigate both the traditional off-line scenario (where
an existing pen-on-paper signature is extracted from a digitised document) as well as the
increasingly popular on-line scenario (where the signature data are automatically recorded
during the signing event by means of specialised electronic hardware). The utilised off-line
feature extraction technique involves the calculation of several discrete Radon transform
(DRT) based projections, whilst on-line signatures are represented in feature space by
several spatial and temporal function features. In order to facilitate writer-independent
signature analysis, these feature sets are subsequently converted into a dissimilarity-based
representation by means of a suitable dichotomy transformation. The classification techniques
utilised for signature modelling and verification include quadratic discriminant analysis
(QDA) and support vector machines (SVMs). The major contributions of this study
include two novel techniques aimed towards the construction of a robust writer-independent
signature model. The first, a dynamic time warping (DTW) based dichotomy transformation
for off-line signature representation, is able to compensate for reasonable intra-class
variability by non-linearly aligning DRT-based projections prior to matching. The second,
a writer-specific dissimilarity normalisation strategy, improves inter-class separability in
dissimilarity space by considering only strictly relevant dissimilarity statistics when normalising
the dissimilarity vectors belonging to a specific individual. This normalisation
strategy is generic in the sense that it is equally applicable to both off-line and on-line
signature model construction. The systems developed in this study are specifically aimed
towards skilled forgery detection. System proficiency estimation is conducted using a rigorous
experimental protocol. Several large signature corpora are considered. In both the
off-line and on-line scenarios, the proposed SVM-based system outperforms the proposed
QDA-based system. We also show that the systems proposed in this study outperform
most existing systems that were evaluated on the same data sets. More importantly, when
compared to state-of-the-art techniques currently employed in the literature, we show that
the incorporation of the novel techniques proposed in this study consistently results in a
statistically significant improvement in system proficiency.

Technické zkoumání listin a platidel, technická ochrana proti padělání / Technical examination of documents and means of payment, technical protection against forgeryŠtalmachová, Martina January 2012 (has links)
The first segment of this magisterial thesis essay offers a theoretical, as well as historical, overview of the issue, describing the foundations, upon which it stands, as well as its development, as addressed in Chapter Two. Chapter Three focuses on the analysis and the condition of the situation in Czech Republic, complimented with visual aides in the form of graphs and other material, in regards to the international field. The essence of this chapter is the comparative consideration of the question of protection against forgery and alterations of means of payment and other documents. The core of the subject, as well as its individual aspects, are then dissected in the following segment beginning with Chapter Four. Discussed here are various forms of protection, mechanisms applied, realized either in the shape of different mechanical devices, as well as a number of safety features embedded in the means of payment itself. The following, fifth chapter, deals with the question of forgery of coins. After this excourse into the field of forgery and protection against it in general, Chapters Six and Seven center around the detection and resolution of criminal activity of this kind, describing the individual methods, analyses, tests and practices used in clarification of answers that are vital to its solving.

A Genuine Dilemma: The Piombino Apollo and Fraud in the First and Second Century Greco-Roman Art MarketGarvin, Kaitlyn 27 October 2016 (has links)
In 1832, fishermen pulled a full-body bronze sculpture of a youth, now called the Piombino Apollo, from the sea near ancient Populonia. Under life-size, the piece resembles an Archaic kouros, though it has some notable unusual features including an inscription dedicating the supposed image of Apollo to Athena and the signatures of two artists found on a lead tablet hidden within the hollow bronze. These unusual features led scholars to eventually reclassify the piece from an Archaic work of the fifth century to an Archaistic forgery of the second or first century.
Few have challenged this reclassification, but this thesis attempts to complicate the application of the word forgery to the Piombino Apollo. Further, it examines whether a contemporary buyer would have been fooled by the sculpture’s “deceptive” traits and offers alternative possibilities to account for the artists’ choices of style, pose, and inscriptions.

Falsificação e autenticidade : a arte como convenção /Anjos, Marlon José Alves dos, 1988- January 2016 (has links)
Orientador: Sérgio Mauro Romagnolo / Banca: José Leonardo Nascimento / Banca: Luiz César Marques Filho / Resumo: As publicações sobre falsificação não raras vezes abordam seus aspectos criminais e antissociais. Essa abordagem não mede esforços para desmascarar, por meio de exames químicos e físicos, obras fraudulentas. Em consequência desse reducionismo, a capacidade questionadora proporcionada pelo ato de falsificar fica ofuscada, reduzindo a obra e o autor, levando em conta apenas a porção criminal contida no ato. Como a autenticidade opera como valor instável, fundamentar o conceito de arte nesse valor é algo temerário. Neste sentido insere-se o presente trabalho cujo objetivo é comentar reflexivamente a falsificação de obras de arte e suscitar possível paralelismo entre ambas. Arte e falsificação têm mais a dizer uma a outra do que um tribunal pode revelar. / Resumen: Las publicaciones sobre falsificaciones no pocas veces ponen en enfoque sus aspectos delictivos y antisociales. Este enfoque se esfuerza para desenmascarar a través de pruebas químicas y físicas, las obras fraudulentas. Como resultado de este reduccionismo, la capacidad inquisitiva proporcionada por el acto de la falsificación se ve ensombrecido por la reducción de la obra y el autor, teniendo en cuenta sólo la parte penal contenida en el acto. Por ser la autenticidad un valor inestable, apoyar el concepto de arte en ese valor es algo temerario. En ese sentido, este trabajo tiene como objetivo comentar obras de arte falsificadas e investigar un posible paralelismo entre ellos. Arte y falsificación tienen más que decir entre sí que podría revelar un tribunal. / Mestre

A Study of Style and Influence in the Early Schools of Violin Making Circa 1540 to Circa 1800Alcorn-Oppedahl, Allison A. (Allison Ann) 12 1900 (has links)
Chapter I of this thesis details contemporary historical views on the origins of the violin and its terminology. Chapters II through VI study the methodologies of makers from Italy, the Germanic Countries, the Low Countries, France, and England, and highlights the aspects of these methodologies that show influence from one maker to another. Chapter VII deals with matters of imitation, copying, violin forgery and the differences between these categories. Chapter VIII presents a discussion of the manner in which various violin experts identify the maker of a violin. It briefly discusses a new movement that questions the current methods of authentication, proposing that the dual role of "expert/dealer" does not lend itself to sufficient objectivity. The conclusion suggests that dealers, experts, curators, and musicologists alike must return to placing the first emphasis on the tradition of the craft rather than on the individual maker.
